Hey folks, not sure if this has been put forward before but I tried this on a troop yesterday.
it involves using adhesive hook velcro (the hard part, not the fuzzy part) and some kitchen scouring pads.
I'd experimented with this, but had never trooped with it in-situ, but it held in place securely and worked perfectly. Moreover, the pads are literally pennies, so can be replaced cheaply. Just rip them out and put in new ones. I suppose they're washable, too
so, you just stick the hook velcro wherever you need padding, press-on the scourer and it's done!
